machine on my broadcast ip

Hi,

I take care of a small network, about 130 systems behind a NAT box. This is one
of 2 networks at this school. It is of constant concern about interference from the other
network individual.
2 of my main feeds go through their network. I am "not allowed" access or control of these feeds.

For a little while I have had strange effects in the network and then while doing a full nmap, I
discover a system on my broadcast IP. ( x.y.z.255 ) The OS is not identified. It says :

Well, thats a solution..
only thing is, you need to have redefine the routing between two subnets.

No - no network changes are made on any network devices. This is strictly done on the local machine. The local machine will still send packets not destined for the local VLAN (192.168.156.0/23) to its gateway. As stated, *if* there are actually machines on a 192.168.157.0/24 network, your local machine will not be able to reach them while you have the subnet mask set "incorrectly."
